Hydrostatic plate bearing

Abstract

The present disclosure relates to a hydrostatic plate bearing, which comprises: a body, and a plurality of restrictors. Wherein, the body is formed with a mounting surface and an oil chamber that are disposed opposite to each other; the plural restrictors includes an orifice restrictor and a membrane restrictor while allowing the orifice restrictor and the membrane restrictor to be serially connected to each other. Operationally, a working fluid that is flowing into the body via the mounting surface is split to flow through the orifice restrictor and the membrane restrictor, in that the split flow of the working fluid that is flowing through the orifice restrictor is guided to flow into the oil chamber.

What is claimed is:  
     
       1. A hydrostatic plate bearing, comprising:
 a body, formed with a mounting surface and an oil chamber that are disposed opposite to each other; and 
 a plurality of restrictors, disposed on the body, including an orifice restrictor and a membrane restrictor that are arranged horizontally and serially connecting to each other. 
 
     
     
       2. A hydrostatic plate bearing comprising:
 a body, formed with a mounting surface and an oil chamber that are disposed opposite to each other; and 
 a plurality of restrictors, disposed on the body, including an orifice restrictor and a membrane restrictor that are arranged serially connecting to each other; 
 wherein, a working fluid that is flowing into the body via the mounting surface is split to flow through the orifice restrictor and the membrane restrictor while allowing the split flow of the working fluid that is flowing through the orifice restrictor to flow into the oil chamber. 
 
     
     
       3. A hydrostatic plate bearing comprising:
 a body, formed with a mounting surface and an oil chamber that are disposed opposite to each other; and 
 a plurality of restrictors, disposed on the body, including an orifice restrictor and a membrane restrictor that are arranged serially connecting to each other; 
 wherein the body has a flow channel and a first chamber formed therein in a manner that the flow channel is arranged in fluid communication with the first chamber while allowing two opposite ends of the flow channel to connected respectively to the orifice restrictor and the oil chamber and also enabling the orifice restrictor and the membrane restrictor to be in serial connection with each other via the flow channel; the membrane restrictor is configured with a thin film and a second chamber in a manner that the thin film is sandwiched between the first chamber and the second chamber; and the working fluid is split into a first fluid and a second fluid while enabling the first fluid to flow sequentially into the orifice restrictor, the flow channel, the first chamber and finally to the oil chamber, and simultaneously enabling the second fluid to flow into the membrane restrictor, and thereby, enabling the respective hydraulic pressures resulting from the first fluid and the second fluid to act upon two opposite surfaces of the thin film. 
 
     
     
       4. The hydrostatic plate bearing of  claim 3 , wherein the flow channel is composed of a first channel and a second channel; the first channel is connected respectively by two opposite ends thereof to the orifice restrictor and the first chamber; the second channel is connected respectively by two opposite ends thereof to the first chamber and the oil chamber; and thereby, a passageway is achieved between the orifice restrictor, the first channel, the first chamber, the second channel and the oil chamber. 
     
     
       5. The hydrostatic plate bearing of  claim 4 , wherein the orifice restrictor has a first hole and the membrane restrictor has a second hole, and thereby, the first fluid is enabled to flow into the first channel through the first hole while the second fluid is enabled to flow into the first chamber through the second hole. 
     
     
       6. The hydrostatic plate bearing of  claim 5 , wherein the mounting surface is formed with a first bypass conduit and a second bypass conduit that are connected to each other while allowing an end of the first bypass conduit that is opposite to an end thereof connecting to the second bypass conduit to be connected to the first hole, and an end of the second bypass conduit that is opposite to an end thereof connecting to the first bypass conduit to be connected to the second hole. 
     
     
       7. The hydrostatic plate bearing of  claim 6 , wherein the first bypass conduit is substantially a channel recessed in the mounting surface by a first depth; the second bypass conduit is substantially a channel recessed in the mounting surface by a second depth; and the first depth is larger than the second depth. 
     
     
       8. The hydrostatic plate bearing of  claim 6 , wherein the body further comprises a plurality of screw holes, each being provided for receiving a bolt; and thereby, the body is fixed on a planar surface of a worktable with the mounting surface of the body facing toward the planar surface. 
     
     
       9. The hydrostatic plate bearing of  claim 8 , wherein the worktable is formed with an opening; the mounting surface has a sealing element disposed thereat in a manner that the sealing element is arranged surrounding the circumference of an area enclosing the plural restrictors and also the circumference of the opening of the worktable; and the opening is arranged connecting to the first bypass conduit and the second bypass conduit for allowing the working fluid to flow into the body via the opening and then to be spit to flow respectively into the first bypass conduit and the second bypass conduit. 
     
     
       10. The hydrostatic plate bearing of  claim 3 , wherein the thin film is made of a flexible metal thin film.
